To detect calls and returns, Callgrind's heuristic
starts with using the jumpkind got from VEX for
a control flow change instruction. However, for
side exits, it always assumed a (conditional) jump,
which holds true for x86, but e.g. not for ARM.
This fixes Callgrind to use the jumpkind found
by VEX for all exits, which should help making
Callgrind work for ARM. It also moves the check
whether a boring jump is actually a fall-through
to instrumentation time. This changes (fixes) the
result for indirect jumps to the next instruction,
which should not be classified as fall-through
(anyway, this case is probably very rare).
This patch introduces an own enum for jump kinds
in Callgrind. This is less confusing than misusing
the VEX jump kind type, as Callgrinds wants
to distinguish BB fall-throughs from real jumps
(which both are Ijk_Boring in VEX).
Also, setup_bbcc now stores separately whether the
jump kind is conditional or not.

When tail recursion optimization is detected (i.e. a jump to the
beginning of the function without creating a new stack frame),
Callgrind collects this as real call (ie. calculates inclusive
call costs), but forgot to dump the call information (the call
type is still left as a jump).
Fixed by also dump call information if inclusive cost is >0.

DARWIN branch. A big ugly DARWIN/trunk sync commit, mostly to do with
changing the representation of SysRes and vki_sigset_t. Functionality of
the trunk shouldn't be changed by it.

This is a little tricky because
* we want to check directly at startup whether the output file
can be written, thus the file name is set at beginning.
* a fork changes the PID in the child, and thus (potentially) the
output file name has to be updated. This best is directly before
generating the profile dump.
* the child after fork needs to be controllable via callgrind_control.
The setup of the control interface needs the new file name, too.
The fix is to allow multiple calls of CLG(init_dumps), everytime the
output file name is needed.

relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.
The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.

In dump.c, gcc complains that 'param max-stack-frame-growth' would be
exceeded, so remove 'inline' spec.
All other warnings are of the form 'call is unlikely and code size
would grow'. These aren't interesting. Remove -Winline.

Prepend the file name of a source file with the directory
if that is available. This not only gets rid of problems with the
same file name used in different paths of a project, but lets
the annotation work out of the box without having to specify any
source directory.
Works both with callgrind_annotate and KCachegrind without any
changes there.
Inspired by Nick's change to cachegrind doing the same thing
in r6839 (and gets rid of a FIXME in the source)

VG_(record_startup_wd) which records the working directory at startup,
and VG_(get_startup_wd) which later tells you what value was recorded.
This works because all uses of VG_(getcwd) serve only to record the
directory at process start anyway. The motivation is that AIX does
not support sys_getcwd directly, so it's easier for the launcher to
ship in the required value using an environment variable. On Linux
sys_getcwd is used as before.

This fixes bug 134316: when an program in callgrind does
a fork, callgrind_control does show both now, and they
can be controlled separately.
However, missing in this patch is zeroing of cost centers
directly after the clone syscall in the child.

the --base option, which allows to specify another
directory for dumps and control/result files.
With "--base=/tmp/foo", we want control/result files
in "/tmp", and not in a directory "/tmp/foo/".
